This is one of the many shots heard around the world in this continuing computer revolution! Great first start man! I can see numerous applications for this. This dude is the next billionaire!

Cool :) You could make the software send touch points with the TUIO protocol and plug it in MT4j.

@NassTechReview They type dmn good i can tell you that. The new ones are to small and don't realy click.

I guess with two scanners, (two line CCDs), one at each axis of the screen, the finickiness can go away even with 10 fingers.

Good Job, I love it

An optical digitizer that doesn't surround the whole screen? Interesting. If I could just stick a sensor bar along the top of any monitor and get reliable multi-touch, that would be great!

Bonus points for the IBM Model M 1391401.

I was working on a similar project with IR receiver LEDs, but failed to work because there had to be too many receivers. Your idea really works! Congratulations. I feature it today in my site.
